Demon Inline
Twins for Blower
Applications
--- the first
to be boost-
referenced

Supercharged?
Have you ever wondered how
to make blower carburetors
respond instantly?

The answer is boost-referencing. By being properly boostreferenced, the power valves in the carburetors become load-sensing devices and respond instantly to the demands of the supercharged engine.

Further, with eight venturi bores aligned with their corresponding intake runners, these Demon Inline Twins offer excellent fuel distribution and atomization. They also eliminate hesitation and surging, and promote a stable idle and crisp throttle response.
  • Available in 525, 625, and 725 CFM models, Demon In-line Twins are the first of their kind to be boost-referenced for Roots-style superchargers

  • Vacuum-operated secondary throttles for street and highway use

  • Compact, side-hung fuel bowls with sight glasses for safe, easy float-level adjustment

  • Simple inline linkage that is easy to adjust and free of spherical bearings and other complications

  • As direct replacements for the Holley 1850, the Inline Twins are easy to install and tune

  • Nostalgic appearance, stunning performance, and surprisingly good fuel economy

  • Two-corner idle adjustment with secondary metering plates standard; electric choke optional

  • Wet-flow tested and baseline calibrated at the factory, each carburetor is shipped with a detailed tuning manual
